Sándor Gaál
Gaál Sándor (born 8 October 1885 in Gogánváralja, Hungary, died 28 July 1972) was a Hungarian accelerator physicist and an alleged co-inventor of the cyclotron. Most credible international sources give the credit of the invention of the cyclotron to American physicist and Nobel Laureate Ernest Orlando Lawrence, who invented the cyclotron during the spring of 1929 and built the first operational cyclotron in 1930 while at the University of California, Berkeley. In November 1939, Ernest O. Lawrence was awarded the Nobel Prize in Physics for his work on the cyclotron and its applications. In his main work, "Fizica teoretica" (Bucuresti, 1957, vol. I, p. 270) Teofil Vescan, professor of Bolyai University in Kolozsvár (Cluj) revealed that Gaál Sándor may have described the cyclotron's working at about the same time as Ernest O. Lawrence during the spring of 1929. In 1929 Gaál allegedly sent a study, with the title ''Die Kaskadenröhre. Ein Beitrag zum Problem der Atomker ...

Particle Accelerator
A particle accelerator is a machine that uses electromagnetic fields to propel electric charge, charged particles to very high speeds and energies to contain them in well-defined particle beam, beams. Small accelerators are used for fundamental research in particle physics. Accelerators are also used as synchrotron light sources for the study of condensed matter physics. Smaller particle accelerators are used in a wide variety of applications, including particle therapy for oncology, oncological purposes, Isotopes in medicine, radioisotope production for medical diagnostics, Ion implantation, ion implanters for the manufacturing of Semiconductor, semiconductors, and Accelerator mass spectrometry, accelerator mass spectrometers for measurements of rare isotopes such as radiocarbon. Large accelerators include the Relativistic Heavy Ion Collider at Brookhaven National Laboratory in New York, and the largest accelerator, the Large Hadron Collider near Geneva, Switzerland, operated b ...

Rolf Wideröe
Rolf is a male given name and a surname. It originates in the Germanic name ''Hrolf'', itself a contraction of ''Hrodwulf'' ( Rudolf), a conjunction of the stem words ''hrod'' ("renown") + ''wulf'' ("wolf"). The Old Norse cognate is ''Hrólfr''. An alternative but less common variation of ''Rolf'' in Norway is ''Rolv''. The oldest evidence of the use of the name Rolf in Sweden is an inscription from the 11th century on a runestone in Forsheda, Småland. The name also appears twice in the Orkneyinga sagas, where a scion of the jarls of Orkney, Gånge-Rolf, is said to be identical to the Viking Rollo who captured Normandy in 911. This Saga of the Norse begins with the abduction of Gói daughter by a certain Hrolf of Berg, (the Mountain). She is the daughter of Thorri, a Jotun of Gandvik, and sister of Gór and Nór. The latter is regarded as a first king and eponymous anchestor of Nórway. After a fierce duell (Holmgang) where none is able to overcome the other, Hrolf and Nór becom ...
